What variants don't deserve their rarity?

Do you know any variants you think deserve to have a higher or lower rarity? A diamond that should be bronze, a gold that should be a diamond? Personally, I think Death Defier should be a Diamond because of how nasty her first SA is, I was shocked when I found out she wasn't (I know she'll get nerfed to oblivion anyway). However, Mystmatch and Freeze Frame should be sent underground. If there was a rarity higher than Diamond, I'd put Heartless and Death Wish there.
